Well-documented outbreaks of human toxoplasmosis infection are infrequently reported.
Here, we describe a community outbreak of multivisceral toxoplasmosis that occurred in Patam, a Surinamese village near the French Guianan border.

From the end of December 2003 through the middle of January 2004, 5 adult patients in Patam, including 2 pregnant women, were initially hospitalized for multivisceral toxoplasmosis. (lire la suite…)

La papillonite ou lépidoptérisme est une dermatose caractérisée par une éruption érythémateuse et micropapuleuse qui se produit après contact avec les fléchettes d’un papillon urticant. […]

C’est en 1912 qu’a été signalée la première épidémie de papillonite en Guyane française. (lire la suite…)

Le travail de thèse vise à modéliser la dynamique spatiale et temporelle d’une maladie à transmission vectorielle comme la dengue, à partir de données environnementales extraites d’images de télédétection.

Un modèle de diffusion, basé sur des données entomologiques et sur des paramètres environnementaux issus d’une image satellitale, est proposé pour décrire la dynamique des moustiques vecteurs de la maladie. (lire la suite…)

Twenty-seven samples of Aedes aegypti (F1 generation) from French Guiana were tested for their susceptibility to dengue serotype 2 virus.

Very high infection rates were observed by indirect fluorescent antibody (IFA) test. Ae. aegypti samples were pooled according to two groups: the first group (N=10) represented mosquitoes from the urbanized area of Cayenne and surroundings, and the second group (N=17) corresponded to mosquitoes collected in the countryside.

A serologic survey for Mayaro virus (Alphavirus, Togaviridae) in 28 wild nonflying forest mammal species in French Guiana showed a prevalence ranging from 0% to 52% and increasing with age.

Species active during the day and those who spent time in trees were significantly more infected, results consistent with transmission implicating diurnal mosquitoes and continuous infectious pressure. (lire la suite…)
